Temperature compensation allows for a second or even a third sensor to be used that that will
influence the units cooling or heating. Return compensation can be used when the supply or
remote sensors are being used for control. Then the return sensor is then monitored to
maintain a minimum return temperature. Supply compensation can be used only when
Optimized Aisle (TW3) is enabled. The supply sensor will not only be used for controlling
cooling capacity but will also monitor the cold aisle temperature to ensure that the cold aisle
temperature setpoint is met.

The return compensation band/value will determine how quickly the cooling capacity is
adjusted as the return temperature drops below the return compensation setpoint.

The Supply Compensation value determines how much the supply temperature setpoint will
be reduced when the units fan speed is at 100% and the cold aisle is not able to maintain
temperature setpoint. Any modifications to the supply temperature setpoint will be shown at
the temperature setpoint on parameter S103 as the actual active control point.

0.01 - 99.99
%/s
0.60 %/s
Controls the rate of change during compressor load changes to avoid overshoots. The filter
value depends on the current control deviation from setpoint. On the setpoints (@ 0% call for
cooling), it's typically set lower (slow).

This parameter should only be adjusted by a factory-service trained technician. The
transition capacity filter controls how quickly the capacity changes between different modes
of operation. This filter helps with the transition to avoid overshoot.

The CW capacity filter controls the rate of change during a valve position adjustment to
avoid overshoots. The filter value depends on the current control deviation from setpoint. On
the setpoint (@ 0% call for cooling), its typically set lower (slower)
